You will ask open questions, rather than closed or questions which limit answers to simple Yes or No. Try to avoid leading questions or questions that involve some suggestion of action. Such shows you do not really think...? Or why do not you do this...? Instead you are seeking a longer more detailed answer and contribution from your workshop participants. For example try asking open questions such as: What options do you see here? What do you think about this suggestion? Where are the advantages of this option? Where are the disadvantages of this option? What do others think about this specific item? Maybe you want to ask an open question to an individual such as, you look puzzled what is on your mind?
